JT-802 Relay Protection Tester

JT-802 Relay Protection Tester

Product Introduction

The JT-802 relay protection tester is a flexible combination of voltage and current output 802 type with standard 4-phase voltage and 3-phase current output, which can easily perform various types of protection tests with various combination outputs. Each phase voltage can output 120V, and the current can output 120A in three parallel. The fourth phase voltage Ux is a multifunctional voltage item, which can be set to four types of 3U0 or detect synchronous voltage, or output any voltage value. The single machine operation convenience device panel is equipped with a trackball mouse, optimized keyboard, and large screen TFT LCD display, with built-in Chinese Windows platform operation software. Ready to use upon startup, easy and fast to operate.
In addition to standalone operation, the dual operation mode can also be connected to an external laptop or desktop computer for operation. Both modes have complete functions and truly complete dual operation mode.
The output end of the new high fidelity linear power amplifier has always insisted on using a high fidelity and high reliability modular linear power amplifier instead of a switch type power amplifier, which improves performanceZhuo YueIt will not cause high or medium frequency interference on the test site, and ensures smooth waveform accuracy from high current to low current throughout the entire process.
The output part of the high-performance host is controlled by DSP, with fast computing speed, strong real-time digital signal processing capability, wide transmission bandwidth, and high-resolution D/A conversion control. The output waveform has high accuracy, low distortion, and good linearity. The device adopts a large number of advanced technologies and precision component materials, and has undergone specialized structural design, resulting in small size, light weight, comprehensive functions, easy portability, and can work immediately after startup. Flow testing is very convenient.
The software has powerful functions and can complete various large-scale complex verification tasks with high automation levels. It can easily test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, and print reports online.
The 802 type device has an independent dedicated DC power output and is equipped with one 110V and 220V dedicated adjustable DC power output.
The complete interface device panel has a built-in keyboard and mouse, which can be operated independently or externally through the keyboard and mouse interface; It also has two USB ports and RS232 ports, which can communicate with computers and other external devices.
The sound self-protection function of the cooling structure design is reasonable, the hardware protection measures are reliable and complete, and it has functions such as power soft start, software self diagnosis of faults, and output locking.
The lightweight, compact, highly integrated single machine and integrated structure adopt a large number of high-tech and carefully designed ultra lightweight structures, making the whole machine extremely small and lightweight.
